Ah good call, I have regen also set to -50 rn

Rest in peace my efficiency, I was so proud of that 7A average battery current :joy:

Caring about efficiency just means your board either doesn’t have a big enough battery or isn’t fast enough to tire you out in 5 miles flat :stuck_out_tongue: All jokes. Here’s a photo of my new BN280’s with the Xcell sleeves on versus my old BN270’s with the stock 10-8 axles and no sleeve, if it helps you see what’s going on there (snapchat photo quality is a bit garbage but i’m too lazy to dig the 270’s from my garage lol)

What’s the name of the setting to enable smart reverse for UART? The only option in METR is specific to nunchuks, and the only throttle response is current control or current control with brake

Ahhh i have no clue, in VESC tool for me it’s a simple toggle to turn it on or off.

Daaamn that looks crisp

Oh god I need to remove the heatsink then :sob:

Quick tip - buying a usb C extension cable will let you plug in and configure the vesc without popping your enclosure open - the best 10 bucks you’ll ever spend.

Keep in mind that high speed and low speed brakes are affected by two different settings, motor regen current and battery regen current.

Passive regen brakes become less and less good the slower they turn, and drops to zero at zero RPM.
If you need to stop on a hill, you should consider running in current-smart-reverse or similar, which allows active braking at low speed to stop you on a hill.

It’s that there’s no room for a cable because the lid blocks it

If I was running any other esc it would have been fine lol

Do you know how to enable it through metr?

Ouch. Not even usb c right angle connectors would help there i guess?

Nah no space for it, I’d have to solder pigtails to the pad instead of the surface mount connector

does the hoyt puck support current bidirectinal?

Until the vibrations rip off the USB jack from your ESC. Be careful of that.

To do anything you want, connect your phone to the same wifi as your computer, then in metr select hamburger > Settings > TCP Bridge and then connect VESC Tool on your computer using the Connection > TCP tab

Mine is wedged up against some foam blocks fwiw, so i should be okay

The [CHUK] settings in metr are the UART settings in VESC Tool.

Yes. But full current reverse is pretty hairy with the puck. The puck has a weird built in throttle curve in the forward direction, but not in reverse. So its a lot more powerful from launch in reverse compared to forward

Ah, I already had it enabled then

Metr - expert - at the very top type “control type” - change setting to current smart reverse - write to esc
